To (bl-l 1071/0111 it puny concern:

Be it known that IJVILLIAM H.Voss, a citizen of the United States, and aresident of Davenport, in the county of Scott and State of Iowa, haveinvented certain new and useful Improvements in Movements for \Vashing-Machines, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a simple mechanical movementfor converting a continuous rotary movement into a rotary reciprocalmovement for washing-machines which utilizes the power applied tooperate it in such manner that heavy work can be performed by the rotaryreciprocal stirrer-shaft with the least possible effort. This Iaccomplish by the means hereinafter fully described, and as particularlypointed out in the claims.

In the drawings, Figure I is a side elevation of a portion of awashing-machine tub with my mprovement applied thereto. Fig. 2 is a planview of the same with the cover removed. Fig. 3 is a horizontal sectiontaken on dotted line 3 3, Fig. I. Fig. 4: is a detail view showing therelative position of the segmental rack and the eccentric pinion whenthe former is at the end of its stroke. Fig. 5 is a detail view of thesegmental rack, looking at one end thereof edgewise.

Referring to the drawings, A represents the cover of a tub of awashing-machine, and B represents the base-plate of a supportingframe(J, which bridges over the same from end to end and aliords bearings forthe operative parts of my invention. The base-plate is arranged in adiametrical position on the cover, and the vertical portion of thesupporting-framearising from the end thereof nearest the circumferentialedge of said cover is provided with horizontal bearings a for thecontinuously-revolving drive-shaft D. The inner end of drive-shaft D isprovided with a beveled drivegear E, which engages a largerhorizontally-disposed gear F, secured on the lower end of a verticalspindle G, which latter is journaled in vertical bearings I; in thehorizontally-disposed reach of the supportingframe. Secured in anddepending from gear F is a stud (K, which preferably has anantifriction-roller ll thereon and enters and engages the walls of aslot 0, extending lengthwise in the transverse end bar H, which latteris made integral with or is secured to one end of alongitudinally-reciprocal rack I. This rack I is provided at its endswith transverse guide-lugsff, which latter engages and slideslongitudinally back and forth upon a suitable guide-rod M. hod M ispreferably rectangular in cross-section and extends from one of thepcrpemlicular legs of the supportingframe 0 to the other and has itsends secured by set-screws in suitable sockets ff in said legs. ()ne ofthese sockets extends through the leg of the supporting-frame in whichit is made, so as to permit of the guide-bar being introduced into orremoved from place longitudinally.

The rack I may be perfectly straight and mesh with and engage a pinion Jon the stirrer-shaft K, which latter is journaled in suitable bearingsin both the overhead horizontal reach of the supporting-frame C and thebaseplate B thereof and extends down through the latter and the cover Aand has a suitable stirrer-head connected to its lower end. I prefer,however, not to make the rack straight, but to make it curved, so thatits teeth will be arranged in a concave line, and I make the axis of thepinion J eccentric to its perimeter, so that the pitch-line of the gearwill be nearer the axis of the stirrer-shaft when the pinion is engagingthe ends of the rack than when it engages it midway said ends, as shownin the drawings. The object of thus arranging the teeth of the rack in acurved line and making the perimeter of pinion J eccentric to its axisis to vary the leverage brought to bear on pinion J at different pointswithin the range of its movement that greater power may be exercised atthe end of the rack where the reversingmovement of the pinion takesplace than at points mediate the same. The stirrer-shaft K is preferablyprovided with a longitudinal groove K therein, and pinion J has aninteriorly-projecting spline which enters said groove, so that saidshaft must revolve with the pinion, but can have an independentlongitudinal movement of its own, so as to enable itto automaticallyaccommodate itself to the volume of work engaged by the stirrer-head Oon the lower end of the same. The upper end of the stirrer-shaft isprovided with a suitable collar 1) to prevent the shaft K from fallingout of its bearings. Vhile I prefer shaft K to have this independentvertical movement, such movement may be dispensed with.

In operation the drive-shaft through the medium of the drive-gear Erevolves the horizontally-disposed beveled gear F, and the lat ter bymeans of a downwardly-projecting stud (l engages a transverse slot inone end of and reciprocates rack I. The rack I slides back and forth ona horizontally-disposed guidebar M and engages the pinion J andthroughit imparts a rotary reciprocal movement to the stirrershaft.

What I claim as new is 1. In a mechanical movement ahorizontallydisposed continuously-revolving drive-shaft, a pinion faston one end thereof, a suspended horizontal gear engaged by said pinionthe shaft of which is independent of the other parts of the movement andarranged at right angles to said drive-shaft having its bearing entirelyabove said gear, which latter has a stud projecting down from its underface, of a vertically-movable rotary reciprocal shaft the upper end ofwhich extends above its upper bearing, a pinion thereon, a reciprocalrack having transversely-slotted means engaged by said stud foractuating said rack, and a suitable supporting-frame arching over saidgearing in which said drive-shaft, shaft of the horizontal gear, and therotary reciprocal shaft are independently journalcd.
